Ambrilia Validates its Targeted Delivery Technology for Cancer in Vivo

MONTREAL, QUEBEC--(Marketwire - June 19, 2008) - Ambrilia Biopharma Inc. (TSX:AMB) today reported that it demonstrated and validated the in vivo proof-of-concept with its NGR-delivery technology applied to a carrier containing a siRNA (small interfering RNA). Data in animal tumor models showed efficient siRNA delivery to the tumor tissue, internalization and suppression of a cancer-promoting gene (oncogene). Such genes are essential to the growth of a number of tumors. In the past years, a number of oncogenes have been suppressed with RNA interference (RNAi), which can be achieved by siRNAs, showing the potential for therapeutic applications in humans.

"This validation represents another significant step forward in our strategy execution for our NGR-directed delivery technology. This latest in vivo proof-of-concept completes our investigation process ahead of schedule. It demonstrates the validation of our targeting peptide for selective and efficient delivery of siRNA, or other anti-cancer agents, thus giving us the green light to intensify our divestment efforts for this asset," said Dr. Philippe Calais, President and CEO. "As delivery remains a major hurdle in siRNA therapeutic developments, this versatile technology has significant potential for any Company active in this field, and now positions Ambrilia well for divestment".

About the NGR-Delivery Technology

Ambrilia's targeted delivery technology uses a proprietary NGR-containing peptide coupled with a drug loaded carrier such as a liposome, a nanoparticle, or other. When the NGR-containing peptide is coated onto a carrier, it results in a selective delivery and internalization of that carrier, and release of the therapeutic load (siRNA or other therapeutics in cancer treatment) in the targeted cells. Ambrilia's NGR-containing peptide has shown specific interactions with a receptor (APN/CD13) which is expressed in many types of cancer cells (melanoma, renal, pancreas, colon, prostate, gastric and thyroid). Furthermore, the carrier, coated with the NGR-containing targeting peptide, enhances the stability of siRNA in vivo, which could lead to improved therapeutic activity.

The Company had previously established a proof-of-concept with doxorubicin, a cytotoxic drug used in cancer treatment, and shown its efficient delivery in animal solid tumor models. Ambrilia aims to divest its NGR-delivery technology by the end of 2008.

Ambrilia's strategy is to capitalize on its broad product portfolio and original expertise in virology. During the course of 2008, execution of the strategy aims to monetize the non-virology assets through third parties agreements, in turn strengthening the Company's financial position to continue building its novel pipeline of antivirals.
